I bought a PS2 because I didn't have a DVD player and wanted a PS2 anyway, so it was a slam dunk. I never bought a dedicated DVD player because I always had a PS2 or PC that could play it. It was the same with PS3 and my Blu-Ray laptop as well.
I often blame the Dreamcast’s lack of DVD support as its ultimate reason SEGA failed in the hardware console with an otherwise unbelievably innovative piece of hardware and incredibly strong software.
Even a DC pro priced at $100 more or whatever might have done the trick to have SEGA in the door first.
